Why are bubbles round?
- thaumasiotes 6y agoBubbles are round because of air pressure. But that doesn't really apply to large holes in the ground. The ground is a lot more difficult to move than a thin soap film is. Most caves aren't round. Most mountains aren't round, and when they are, it's for different reasons.
